I found this game on the No Bullshit Games page, which lists games that don't have IAPs or ads. So generally they cost a couple bucks, and I believe this one did.
I really like the mechanics of this game. Little agents move around your system of facilities automatically performing tasks. It reminds me of the World/Kingdom of Keflings which I played nigh on a decade ago. Setting up automated systems like this is one of my favorite game mechanics.
I don't like that the campaign levels are so short. It seems like I could get more enjoyment out of the effort I put into setting everything up. Actually these short levels would be OK for a few tutorial levels, maybe even 10 learning levels. But it keeps going, and with seemingly random new things mixed in. I have passed level 27 in the campaign and it keeps throwing in new concepts that are only used for one or two levels. By now I am maybe four hours into the game and I am tired of learning one-off things.
It would help a lot of the buildings and/or resources were intuitively named. Gumballs are made in a laboratory? How am I supposed to remember that? Maybe it should be called...a gumball factory!
At this point I don't really feel like completing the campaign.
